/*
|

* File: bmtable.c
|
||||
* Purpose: Implementation of the XForms object bmtable.
|
||||
* Author: Alejandro Aguilar Sierra <asierra@servidor.unam.mx>
|
||||
* Created: November 1995
|
||||
* Description: A bitmap table uses a single bitmap to simulate a 2d array
|
||||
* of bitmap buttons. It can be used to build bitmap menus.
